Be it known that 1, JOHN W. HIER, a

citizen of the vUnited States, residing at Huntington, in the county of Huntmgton' and State of Indiana,

have invented new and useful Improvements in "Garbage and Refuse; Incinerators, or which the following is a specification, v f b This invent'on relates to garbage' and refuse incinerators of the type wherein garbage or refuse is fed into the incinerator from the top and drawn oli througha suitablewithdrawal o cning ontheside.

The principal o jectof the invention is to improve and simplify the general construction of devices of this character. A second object of the invention to providean improved construction of incinerator wherein the course orpath of the hot i gases used to dry out and mcinerate the garbage or refuse will befso regulated as to provide increased economy in fuel consumption and increased eiiiciency in operation.

A third object of the invention 1s the provision of improved means in the incinerator for the economical production of a supply of steam adapted to be utilized for the treatment of the garbage or refuse atcertain times in the incinerating operation.

A fourth object of the invention is the provision of an improved arrangementof air space surrounding the incmerat ng chamber and having communication therewith and means for controlling the admis sion of free air thereto.

With the above and other objects in view, the invention consists in general of certain novel details of construction and combination of parts hereinafter fully described,

illustrated in the accompanying drawings and specifically claimed.

In the accompanying acters of reference indicate like parts in the several views, and

Figure 1 is a section on the line l-1 of Fig. 2;

Fig. 2 is a view partly in front elevation and partly in section'on the line 2-2 of Fig 1' 9 F1g. 3 1s a section on the -hne' 3-3 of Fi 1; and

hig. 4; is a section-on the line 1-4 of Fig. l In carrying out the objects of the invention I preferably group twa, furnaces, A B together in acommon setting 10, one being top: of the roof, this opening beln ali'ned 'Wlfih a similar opening 18 through t e outer st andin drawings, like chara right-hand furnace and the other a left-- hand furnace. Each of these furnaces, .consists' of a' substantially dome-shaped outer shell 11 having the general form of an elongated hemisphere and between this outer shell and the setting is a packing of rammed cinders or the like.

. Spaced within the outer'shellillis an in- ;damper 16 is provided.- Thisair space 14: furthermore communicates with the interior of the furnace through an opening 17 at the shell 11 and dumping floor 19. Normally, the openinglS is closed by a plug valve 20. One side of the furnace is'fiattened, as at 21, and adjacent this side'is a fire grate 22 extending over an ash pit 23, suitable come ting 10 by the fuel feed and ash pit' door openings 24 and 25. r v

Disposed centrally of the :width of the furnace is a passage 26, the ends ofwhich are separated by a bridge Wa1l'27. The inner end of this passage is covered by a grating 28 disposed directly below the openings 17 and 18 while a draw-off grate 29 covdraw-ofi' grate is an arch 30 opening outward through a door opening 31,;the end 26 opening outward through'a door opening 32. Between the grates 22 and 29 is an upbafile 33 so that the flames and gases of combustion will-follow the path of the arrows, a, the air currents being indicated by the-arrows (Z.

ner shell 13 concentric to'the outer shell so munication being afforded through the seters the outer end of the passage. Overthis stack 34: which communicates with the furnaces by fines 35 controlled by dampers 36.- By-passes 37 lead from the lines 35 to an up-take 38 which communicates with a tubular boiler 39 having valve controlled inlet and outlet pipes 40, the boiler being Inounted in a, suitable enlargement of the up-take which has communication with the stack through a passage 41 contro led by a damper 42. By this means the boiler may -be used,when desired, to generate steam for the purposes of using the same to increase the drafts, operating a drying fan or any. other desired purpose, the connections for these different purposes not being deemed necessary to be shown as such connections form no ,part of the present invention.

In order to insure both proper drainage and the proper flow of the products of combustion,-the floor of the furnace'is made in the form of a helix, theaxis of which is the center line, so that all the drainage from the mass of refuse to be incinerated Will flow toward the center, While, at the same time, the axis of the cone formed by dumpingmaterial down the openingl8 will be slightly tilted to one side to cause distribution of the flame and gases of combustion. To aid in this drainage I further provide curved pasvand material dried out, what may be termed the free liquid drawing off-through the grate 28 or passing down, through the'openings 4.3. By manipulating the dampers, the hot gases may be sent either through the stack direct or through the boiler.

There has thus been provided a simple and eflicient device of the kind, described and for the purpose specified.

Having thus described my invention, I claim 1. A refuse incinerator, inner andouter furnace shells separated to provide an air space between said shells, an incinerating chamber of substantially velongated domeopening to the exterior.

dome-shaped shells forming an shape having a fire gfate adjacent one end and a Withdrawal grate intermediate the ends, a battle extending upward from floor to roof of the chamber between the grates, and valve-controlled. means the air space between the shell.

A refuse incinerator including a chamher having an inner and outer shell'separated to provide an air passage having communication with the interior of the chamber at the top thereof, va1ve=contro1led means for admitting air to the ail spaceand to the, interior of the inner shell, the chamber fur-- ther having a helical floor with its lowest point located perpendicularly beneath the communicationbetween the air passage and the chamber, the floor of the chamber having an opening at its lowermost point, a

-grat1ng covering said opening,-' ;he incinerator having a passage leading from the comprising incinerating spaced from each 3'. A garbage incinerator,

chamber, the shells bein other to form an air-heatlngcha-mber, afirebox in communication with the incinerating chamber, the shells having alined feed openings atthe top thereof, and said. air chamher being incommunicationwith the outer atmosphere and with said feed openings.

In testimony whereof I have hereunto set my hand in presence of twosubsc'ribing witnesses. I
